System and method for physical downlink control channel monitoring

ABSTRACT

Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH). A first time gap is set from an end of the PDCCH to a beginning of a physical downlink shared channel (PDSCH). A second time gap is set from an end of the PDSCH to a beginning of a physical uplink control channel (PUCCH). A high priority channel and a low priority channel are configured in a PDCCH monitoring span. At least one parameter indicating a minimum amount of additional time required by a user equipment (UE) for processing the low priority channel, is received from the UE. Based on the at least one parameter, the UE is configured with at least one offset used to increase at least one of the first time gap and the second time gap.

PRIORITY

This application is based on and claims priority under 35 U.S.C. § 119(e) to a U.S. Provisional Patent Application filed on Oct. 14, 2019 in the United States Patent and Trademark Office (USPTO) and assigned Ser. No. 62/914,924, the contents of which are incorporated herein by reference.

FIELD

The present disclosure relates generally to channel monitoring, and more particularly, to physical downlink control channel (PDCCH) monitoring for a span configured for both high priority and low priority channels.

BACKGROUND

In 3^(rd) Generation Partnership Project (3GPP) 5^(th) Generation (5G) Release 16 (rel-16), enhanced PDCCH monitoring occasions for ultra-reliable low latency communication (uRLLC) were presented. Additionally, user equipment (UE) control channel element (CCE) and blind decoding (BD) capabilities were defined per span, rather than per slot. A span is a number of consecutive symbols in a slot where the UE is configured to monitor PDCCH. A span is defined based on configured search spaces (SSs) and monitoring occasions (MOs) for a given serving cell, and based on a set (X, Y) reported by a UE. X is the gap between the start of two consecutive spans, and Y is a span length in symbols. A span starts at a first symbol where a PDCCH MO starts and ends at a last symbol where the PDCCH MO ends. The same span pattern repeats in each slot.

For 5G Release 15 (rel-15) capability, BD/CCE limits are defined per slot as a function of sub-carrier spacing (SCS) of the cell. For 5G rel-16 capability, the BD/CCE limits can be defined per span.

When a UE supports both 5G rel-15 capability and 5G rel-16 capability, PDCCH monitoring is performed for both enhanced mobile broadband (eMBB) (low priority channels) and uRLLC (high priority channels).

For a 5G UE that supports an enhanced PDCCH monitoring capability, PDCCH monitoring based on 5G rel-15 capability for eMBB and PDCCH monitoring based on 5G rel-16 capability for uRLLC may be configured to the UE on the same carrier. Specifically, the UE is configured with mixed slot-based and span-based PDCCH monitoring on a serving cell. For the 5G PDCCH monitoring capability, a limit on the maximum number of non-overlapping CCEs for channel estimation per PDCCH monitoring span is the same across the different spans within a slot.

The UE performs BD/CCE monitoring per slot for eMBB and performs BD/CCE monitoring per span for uRLLC. uRLLC search spaces (SSs) and eMBB SSs may correspond to different control resource sets (CORESETs). uRLLC SSs and eMBB SSs also have a different SS identifiers (IDs), when having the same CORESET. uRLLC and eMBB can also be differentiated based on a corresponding downlink control information (DCI) format or size. Accordingly, the UE is able to determine whether a given BD/CCE corresponds to uRLLC or eMBB prior to processing the corresponding PDCCH candidate.

If the UE has two processing pipelines, the UE is able to route the BD/CCE to one of the two pipelines according to service type or priority (e.g., high priority uRLLC or low priority eMBB). Alternatively, if the UE has a single pipeline, the UE prioritizes the BD/CCE candidates of uRLLC over the BD/CCE candidates of eMBB. For example, the UE first processes all of the BD/CCE candidates of uRLLC in a given span, and only when it has finished, will the UE begin processing the BD/CCE candidates of eMBB. However, such a prioritization may result in an inability to meet a timeline for eMBB processing.

For example, according to one embodiment, a module may be implemented in a form of an application-specific integrated circuit (ASIC).

According to an embodiment, when a UE operates mixed slot-based and span-based on a serving cell, and is not able to process both uRLLC and eMBB traffic simultaneously, additional minimum processing time is provided for the eMBB PDCCH, PDSCH, PUSCH, or other types of eMBB channels. The extra processing time is determined according to UE capability signaling and RRC configuration signaling.

Thus, the UE is able to process both eMBB and uRLLC control and data channels without any significant impact on their respective requirements. A latency requirement of uRLLC is unaltered, while a latency requirement of eMBB is adjusted by a small amount.

With eMBB processing time relaxation, the UE processes the eMBB with an increased PDCCH-to-PDSCH or PDSCH-to-PUCCH or PDCCH-to-PUSCH time gap.

Referring initially to FIG. 1, a diagram illustrates a span configured with two MOs for uRLLC and one MO for eMBB, according to an embodiment. Within a span 102 of PDCCH, the UE performs BD/CCE processing for uRLLC at a first MO, MO1 104, and a third MO, MO3 108. Once processing is completed in the MO1 104 and the MO3 108, the UE performs BD/CCE processing for eMBB at a second MO, MO2 106.

If the MO1 104 and the MO3 108 do not exist in the span 102, and only eMBB is scheduled in the MO2 106, a scheduling offset gap To and a PDSCH-to-hybrid automatic repeat request (HARD) gap T₁ are set based on minimum processing time capabilities. T₀ is the time gap between an end of the PDCCH in the span 102 and a beginning of an eMBB PDSCH 110. T₁ is the time gap between an end of the eMBB PDSCH 110 and a beginning of an eMBB HARQ-acknowledgement (ACK) 112 (i.e., PUCCH). T₀ is determined by the time-domain resource allocation (TDRA) field in eMBB DCI, and T₁ is determined by the PDSCH-to-HARQ-ACK slot-based gap field and PUCCH format indicator (PFI) field in eMBB DCI.

However, with the addition of the MO1 104 and the MO3 108 to the span 102, and the resulting processing of both eMBB and uRLLC in the span 102, eMBB processing time relaxation is provided through the addition of an offset d₀≥d₀ ^(offset,cap) to T₀ and/or an offset d₁≥d₁ ^(offset,cap) to T₁.

The parameter d₀ ^(offset,cap) is a UE capability parameter that indicates a minimum additional time that the UE requires for PDSCH reception at the eMBB PDSCH 110. The parameter d₁ ^(offset,cap) is a UE capability parameter that indicates a minimum additional time that the UE requires for HARQ-ACK preparation for the eMBB HARQ-ACK 112. These two parameters are provided from the UE, to a BS. The parameter d₀ ^(offset,cap) may be reported for different values of SCS (scheduling cell and scheduled cell), and the parameter d₁ ^(offset,cap) may be reported for different values of SCS (scheduled cell and UL cell for PUCCH transmission).

The BS determines the offsets d₀ and d₁ based on the corresponding received parameters, and configures the UE via RRC. Specifically, the offset d₀ is added to T₀ to increase the time between PDCCH and PDSCH, and the offset d₁ is added to T₁ to increase the time between PDSCH and HARQ-ACK (PUCCH). The UE may be configured with the offset d₀ for different values of SCS (scheduling cell and scheduled cell), and may be configured with the offset d₁ for different values of SCS (scheduled cell and UL cell for PUCCH transmission).

Referring now to FIG. 2, a diagram illustrates a span configured with two MOs for uRLLC and one MO for eMBB, according to another embodiment. Similar to the embodiment of FIG. 1, within a span 202 of PDCCH, the UE performs BD/CCE processing for uRLLC at a first MO, MO1 204, and a third MO, MO3 208. Upon completion of processing of the MO1 204 and the MO3 208, the UE performs BD/CCE processing for eMBB at a second MO, MO2 206.

If the MO1 204 and the MO3 208 do not exist in the span 202, and only eMBB is scheduled in the MO2 206, a scheduling offset gap T₂ is set based on a minimum processing time capability. T₂ is the time gap between an end of the PDCCH and a beginning of an eMBB PUSCH 214. T₂ is determined by eMBB DCI.

With the addition of the MO1 204 and the MO3 208 to the span 202, and the resulting processing of both eMBB and uRLLC in the span 202, eMBB processing time relaxation is provided through the addition of an offset d₂≥d₂ ^(offset,cap) to T₂. The parameter d₂ ^(offset,cap) is a UE capability parameter that indicates a minimum additional time that the UE requires for PUSCH transmission at the eMBB PUSCH 214. The parameter is provided from the UE to the BS. The parameter may be reported for different values of SCS (scheduling cell and PUSHC cell).

The BS determines the offset d₂ based on the received parameter, and configures the UE via RRC. Specifically, the offset d₂ is added to T₂ to increase the time between PDCCH and PUSCH. The UE may be configured with the offset d₂ for different values of SCS (scheduling cell and PUSHC cell).

According to an embodiment, the UE also adds the offset d₀≥d₀ ^(offset,cap) to T₀, the offset d₁≥d₁ ^(offset,cap) to T₁ and/or the offset d₂≥d₂ ^(offset,cap) to T₂, when different MOs corresponding to different service types or priorities (uRLLC with high priority and eMBB with low priority) are configured in a slot, as opposed to a span, as described above in FIGS. 1 and 2.

An aperiodic channel state information (CSI) request/reporting time offset, or a sounding reference signal (SRS) transmission time offset may be defined as time gap T_(other). When different MOs corresponding to different service types or priorities (uRLLC with high priority and eMBB with low priority) are configured in a slot or a PDCCH MO span, the UE may add an offset d_(other)≥d_(other) ^(offset,cap) to T_(other). The time gap T_(other) is indicated in eMBB DCI. The parameter d_(other) ^(offset,cap) is a UE capability parameter that indicates the minimum additional time that the UE requires for eMBB processing. The UE provides the parameter to the BS, and the BS configures the UE with the offset d_(other) via RRC signaling.

Scheduling time gaps T_(i) and added offsets d_(i) may be defined in terms of time (seconds) or OFDM symbols (OS). The scheduling time gaps T_(i) and added offsets d_(i) can be a function of numerology or SCS of the serving cell (scheduled or scheduling).

The UE can assume relaxation for eMBB processing time (i.e., one or more of the added offsets are non-zeros), if uRLLC traffic is scheduled in the uRLLC MOs in the span or slot. Specifically, eMBB relaxation is not assumed if uRLLC is not scheduled in the span or slot.

The UE can assume that relaxation is not provided for eMBB processing time (i.e., the added offsets are zeros), if there is a first minimum number of OFDM symbols between an ending symbol of the latest uRLLC MO (e.g., the MO1 104 of FIG. 1, or the MO1 204 of FIG. 2) and a starting symbol of the eMBB MO (e.g., the MO2 106 of FIG. 1 or the MO2 206 of FIG. 2), and if there a second minimum number of symbols between the ending symbol of the eMBB MO (e.g., the MO2 106 of FIG. 1 or the MO2 206 of FIG. 2) and a starting symbol of a next uRLLC MO (e.g., the MO3 108 of FIG. 1, or the MO3 208 of FIG. 2).

FIG. 7 is a block diagram of an electronic device in a network environment, according to one embodiment. Referring to FIG. 7, an electronic device 701 in a network environment 700 may communicate with an electronic device 702 via a first network 798 (e.g., a short-range wireless communication network), or an electronic device 704 or a server 708 via a second network 799 (e.g., a long-range wireless communication network). The electronic device 701 may communicate with the electronic device 704 via the server 708. The electronic device 701 may include a processor 720, a memory 730, an input device 750, a sound output device 755, a display device 760, an audio module 770, a sensor module 776, an interface 777, a haptic module 779, a camera module 780, a power management module 788, a battery 789, a communication module 790, a subscriber identification module (SIM) 796, or an antenna module 797. In one embodiment, at least one (e.g., the display device 760 or the camera module 780) of the components may be omitted from the electronic device 701, or one or more other components may be added to the electronic device 701. Some of the components may be implemented as a single integrated circuit (IC). For example, the sensor module 776 (e.g., a fingerprint sensor, an iris sensor, or an illuminance sensor) may be embedded in the display device 760 (e.g., a display).

The processor 720 may execute, for example, software (e.g., a program 740) to control at least one other component (e.g., a hardware or a software component) of the electronic device 701 coupled with the processor 720, and may perform various data processing or computations. As at least part of the data processing or computations, the processor 720 may load a command or data received from another component (e.g., the sensor module 776 or the communication module 790) in volatile memory 732, process the command or the data stored in the volatile memory 732, and store resulting data in non-volatile memory 734. The processor 720 may include a main processor 721 (e.g., a central processing unit (CPU) or an application processor (AP)), and an auxiliary processor 723 (e.g., a graphics processing unit (GPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operable independently from, or in conjunction with, the main processor 721. Additionally or alternatively, the auxiliary processor 723 may be adapted to consume less power than the main processor 721, or execute a particular function. The auxiliary processor 723 may be implemented as being separate from, or a part of, the main processor 721.

The auxiliary processor 723 may control at least some of the functions or states related to at least one component (e.g., the display device 760, the sensor module 776, or the communication module 790) among the components of the electronic device 701, instead of the main processor 721 while the main processor 721 is in an inactive (e.g., sleep) state, or together with the main processor 721 while the main processor 721 is in an active state (e.g., executing an application). The auxiliary processor 723 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module 780 or the communication module 790) functionally related to the auxiliary processor 723.

The memory 730 may store various data used by at least one component (e.g., the processor 720 or the sensor module 776) of the electronic device 701. The various data may include, for example, software (e.g., the program 740) and input data or output data for a command related thereto.

To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

One embodiment may be implemented as software (e.g., the program 740) including one or more instructions that are stored in a storage medium (e.g., internal memory 736 or external memory 738) that is readable by a machine (e.g., the electronic device 701). For example, a processor of the electronic device 701 may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. Thus, a machine may be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include code generated by a complier or code executable by an interpreter. A machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term “non-transitory” indicates that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.

According to one embodiment, a method of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., Play Store™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.

According to one embodiment, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities. One or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In this case, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. Operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
